NEW ADVANCEMENT ON DEVELOPMENT TECHNIQUES IN SICHUAN GAS FIELDS

LI Lu-guang(PetroChina Southwest Oil & Gasfield Company)  
Since 2000,natural gas trading is growing rapidly in PetroChina Southwest Oil Gasfield Company,and the annual gas production increase ratio has been up to more than 10%.Actually the company has to face up with many difficulties like high-sulfur gas fields to be postponed for some reason,great technical intractability encountered in the large-scale development of Upper Triassic Xujiahe Formation gas reservoirs,and the depletion of old gas fields obviously on the increase,but on the other hand,during their painstaking exploration works on those four areas including large gas fields,high-sulfur gas fields,Xujiahe formation gas reservoirs,and the previous old gas fields,all kinds of techniques have been integrated and innovated into nine matured and characteristic items of technology,such as the technology on fine gas reservoir description,which help the company to achieve in great success in natural gas trading.Especially in 2007,failing to obtain the previously predicted 2.2 bcm of gas production from the high-sulfur gas field,the company succeeded in producing 14.471 bcm this year,1.043 bcm more than that in 2006,with an increase ratio of 7.77%.
